WILLIAM JJMAGEE, OF ST. LOUIS, MISSOURI. v

PRESSURE AND SUCTION BLOWER.

To all whom it may concern;

Be it known that I, WILLIAM J. M tGEE, a citizen of the United States, and a resldent of St. Louis, Missouri, have invented certain after described-and claimed.

This invention consists of a revolvm member within a casing for creating a rapi current of air to be distributed through tubing to any point.

The object of this invention is to provide a revolving member with passages terminating outwardly from the axis collecting air and delivering it under pressure through said passa es into the casing from whence it is distri uted.

A further object of my invention is to provide a blower having a revolving member consisting of a hub-section to which is attached s set metal sections or-box blades which form the passages through which the air is delivered into the casing of the blower, and by such construction, the revolving member is made light and more effective than if the same were cast of solid material.

In the drawings Figure 1 is a side view of my complete invention with a art broken away and in section, showing tl ie construction and relative position of the various parts. Fig. 2 is'a horizontal, central, sectional view of the same. Fig. 3 is an enlarged detail view with parts in section, showing the bearing and relative position and construction of the shaft to which the revolving member is secured. Fig. 4 is an end view of one of the arms of the revolving member, showing its construction. Fig. 5 is a sectional view of the hub member taken on the line 55 of Fig. 6. 'Fig. 6 is a central, sectional view of the same taken on the line 6-6 of Fi 5. Fig. 7 is an enlarged detail, sec-- tiona yiew of auportion of .the hub showing its flanges and the manner in which the arms are attached to the same.

In the construction of my invention I provide the casing 8 provided with a suitable base 9 by which the same is supported to any suitable baselate, and the oneend is terminated into an outlet 10. The sides 11 of the casing are provided with openings 12 which it Specification of Letters IPatent. Application filed January 22. 1907. 'Serial No. 363.486.

correspond in size with the inner periphery of the hub-section 13' of the revolving member. The sides 11 of said casing are provided with large openings in which are inserted and held by bolts or the like, flange-sections 14. The object of arranging the flanged sections 14 in this manner, which practlcally forms the sides of the casin is to permit the insertion and removal of t e entire revolving section when so desired.

In the casing I provide a revolving memher which conslsts of a hub-section 13 mounthub-section is preferably cast and all ofits parts formed inte al, and to the flanges 20 and 21 are suitabI; held by means of rivets or the like, the sheet metal arms or box blades 23; the side 24 of the arms being held to the flange 20 and the side 25 of the arms being held to the flange 21 by the rivet 26, the end of said side being turned up as indicated by the numeral 27 and supported together with the side 24 to the flange 20 by means of the rivets 28.

The arms 23 are preferably constructed of two sections .of sheet metal connected together by the lap-joint 29 as shown in Fi 4, thus dispensing with the use of rivets w 'ch have a tendency to shear while the revolving member is in rapid revolution. It is my intention to dispense with the use of as many rivets as osslble, es ecially in the construction of t e arms. he arrangement of the arms to form the passages 30 have then base portion, or, in other words, the end to which they are secured to the hub, of lar er diameter than the outlet 31, and the si es 24 and 25 are curved sufliciently to provide a suitable suctionand free, delivery of the air throughthe passage into the blower casing. In order to prevent a leakage within the blower casing, I make a complete contactbetween the rings 22 of the hub and the pro ection 32 formed at the openings 12 and 15 (See Fig. 2). In addition to sup ortmg the arms to the flanges 20 and 21, rivet the base of the arms to the rings 22 as indicated by the numeral 33.

The revolving member is placed in operation by the pulley wheels 34 mountedu on provided a plurality of erforations- 35 through which air is admitte to circulation I while the revolving member is in operation which the tubing is connected and form the opposite wall of the casing solid with a hole of the proper diameter for the free movement 1 of the driving, shaft. Otherwise the construction of the pressure blower and suction blower is the same.

Having fully described my invention, what I claim is: i

1. A device of the class described, comprising a blower casing, a shaft, a hub mount- -ed upon saichshaft within the blower casing, spokes radiating. from the hub, flanges formed on the ends of said s 'okes, hollow sheet metal arms composed 0 two sections and retained together by lalp-joints, said described, com

prising a revolving member composed of a hub member, a lurality of flanged spokes forming a part 0 the hub member, a pair of rings formed on the sidesof the hub member forming a part thereof, a plurality of hollow tions and retained together y lap-joints, the base of each of said arms attached to the flanged ends of the spokes and the rings in combination with a blower casing in WhlCll the revolving member is revolubly mounted,

substantially as specified.

sheet metal arms each composed of two sec-
